Video Settings

The Video tab controls how your device screen is captured and displayed. These settings apply each time you start a new mirroring session.

Quality​

Bit Rate​

Controls how much data is used per second for the video stream. Higher values produce a sharper, cleaner image but use more bandwidth and CPU.

  • For USB: you can safely use high values without network concerns
  • For Wi-Fi: lower values reduce stuttering on slower networks

Leave at the default if you are unsure.

Max Resolution​

Limits the maximum resolution of the mirrored image. Reducing this improves performance on slower devices or older computers.

Frame Rate​

Max FPS sets the maximum number of frames per second. Lowering it reduces CPU usage and device battery drain. Raising it produces smoother motion, useful for games or video playback.

Common choices:

  • 15 fps — low performance mode
  • 30 fps — balanced (default)
  • 60 fps — smooth, higher resource use
  • 120 fps — requires a device that supports high frame rate capture

Codec​

The codec determines how the video is compressed before being sent to your desktop.

CodecBest for
H.264Maximum compatibility, works on all devices
H.265Better image quality at the same bit rate
AV1Highest efficiency, requires Android 14+

If you see a launch error about the codec, switch back to H.264.

Orientation​

Capture Orientation​

Sets the orientation in which the device screen is captured. Useful when you want to mirror in landscape without rotating your desktop window.

Display Orientation​

Rotates the image as displayed in the mirror window. This does not affect the actual device orientation.

Rotation Angle​

Fine-tune the rotation in 90° increments independently of the capture and display settings.

Crop​

Defines a sub-region of the screen to mirror instead of the full display. Enter the region as Width:Height:X:Y, where X and Y are the top-left corner of the crop area.

For example, to capture a 800×600 area starting at position (100, 50), enter 800:600:100:50.

Leave blank to mirror the full screen.

Buffering​

Adds a small delay to the video stream to smooth out momentary hiccups. Increase this if the video is choppy. Leave at the default (or zero) for the lowest possible latency.

No Video​

When enabled, the video stream is disabled entirely and only audio is forwarded. The mirror window will not open. This is useful for listening to device audio through your desktop speakers without the screen.
